安装OpenPCDet时，
python setup.py develop
报错：

解决

可见，最初的错误是：

CUDA unknown error - this may be due to an incorrectly set up environment, e.g. changing env variable CUDA_VISIBLE_DEVICES after program start. Setting the available devices to be zero.

在

上找到解决方法：

apt-get install nvidia-modprobe

This works for me.

这个也work for me.

The nvidia-modprobe utility is used by user-space NVIDIA driver components to make sure the NVIDIA kernel module is loaded and that the NVIDIA character device files are present. These facilities are normally provided by Linux distribution configuration systems such as udev.
